Abstract
The 90° cross section yield curve for the (n,C reaction has been measured from (13.4) to 17.0(24.0) MeV. Angular distributions of cross section and analyzing power were measured at seven energies spanning this excitation region. In addition, the fore-aft asymmetry and 90° analyzing power were measured as a function of energy from to 17.0 MeV. The data were compared to direct-semidirect model calculations which included the isovector dipole and isoscalar electric quadrupole transitions. These comparisons indicate the presence of two narrow M1 resonances at =16.5 and 17.5 MeV and that σ(E2) is less than 2% of the total capture cross section in the energy region of this experiment.
